In the course of design, we fully consider the actual conditions on the railway and take a series of corresponding measures to the concrete problem. such as we select high - accuracy microconvertor and have the converted function in succession data collecting system chip aduc812, design v / f circuit and external a / d circuit. in anti - interference of the hardware, we try to disperse each function module to avoid interfering each other, adopt photoelectric isolated technology to dispel the circuit connection of input and output. in controlling we import arithmetic mean into strain wave algorithm and real computing technology of virtual value for sample treatment of data, that is using the software to smooth away interfere error and to calculate actual value, thus it makes the precision of the data improve greatly
在設計過程中，根據系統要求，充分考慮鐵路上的實際情況，針對具體問題採取了一系列的相應措施，如在器件選擇方面選用高精度microconvertor系列、具有adcdma連續轉換功能的數據採集微控制器晶元aduc812 ，設計了v f變換電路和外部a d轉換電路；在硬體抗干擾方面，將每個功能模塊盡量分散獨立開來以避免相互干擾、採用光電隔離技術消除輸入輸出通道上的電路聯系；在控制方面對于采樣數據的處理引入了算術平均值濾波演算法和真有效值的計算方法，即通過使用軟體來濾除系統中有干擾造成的誤差並計算真值，從而使數據的準確性得到極大地提高。 -
Examinations show that our arithmetic can make good use of hvs system, and is robust to common image processing such as noise, mean - filter, sub - sample and jpeg compress. string - type watermark is more robust
經過試驗檢驗，該演算法不僅能很好地結合hvs系統，且對一般圖像處理（對抗噪聲、均值濾波、亞抽樣和jpeg壓縮）都具有好的魯棒性，字元型水印的效果更佳。
